Fix 32-bit overflows in LLVM composite constants Inspired by #121868. Fixes unsoundness created when constructing constant arrays, strings, and structs with 2^32 or more elements on x86_64. This introduces copies of a few LLVM functions that have their signatures updated to use size_t in place of unsigned int. Alternatively we could just add overflow checks and just disallow huge composite constants. That introduces less code, but maybe a huge static block of memory is useful in embedded/no-os situations? |
